Via Kings of War and Colonel Phil Ridderhof, USMC, (H/T to both) - The UK's Joint Doctrine Publication (JDP) 3-40: Security and Stabilisation: The Military Contribution.
JDP 3-40 provides joint, operational level doctrine for the military contribution to stabilisation.
This will usually take place during or immediately following conflict and in the context of weak or failed states that face a range of challenges to governmental authority that range from criminality to insurgency.
JDP 3-40 identifies the general priorities for stabilising failed or failing states, and determines the nature, level, principles and priorities that govern the UK military contribution and the guidelines governing transition to civilian and host nation control.
